God is awesome!

in your vehicles owner manual, look up fuses, and flasher units or flasher relay. Fuses are normally located under the dash, but when both turn signals quit working it is usually the relay. The relay is located under the hood yours owners manual should show you the location.

checked all fuses even under hood? may have bad signal switch or bad brake light switch yes even if 3rd brake works.also check wiring under rear fender by bumper thats were wire harness is hope this helps.

After checking the fuses I would replace the fuse for the tail lights just to make sure it wasn't a fuse issue and if that doesn't do it I would check the bulbs on both sides to make sure that the bulbs are good.
